On the Shield Gas Box, there are two LEDs displaying the status of the CAN-bus module. The states of these lights
are shown in the table below.

Yellow
In normal operation, the green LED indicating the power must be ON. When the station is selected, the yellow
LED should be ON all the time; and green LED will flash 90% ON and 10% OFF. Otherwise, there is a problem.
1. If the green light is not on, check the power input (cale connection) and fuse.
2. If the yellow light is not on and the green light is on, check can-bus connection. Make sure the sta-
tion is selected.
